T0 all whom t may concern:

Be it known that we, JOHN A. MANsoN and JOHN W. MACKLEM, citizens of the United States, and residents of Battle Greek, in the county of Ida and State of Iowa, have invented cei't-ain'new and useful improvements in Hog Gates, of which.

the following is a speci'lication. f

Our invention relates to devices or protecting small, partly grown hogs from oonstant Contact with full grown hogs, and it is our object to'provide orthis purpose a swinging gate of, simple, durable and inexpensive construction, adapted to selectively exclude passage of the larger hogsrinto the individual pens or houses provided for the smaller hogs, and also adapted to allow passage of the smaller hogs only in the direction leading into such individual pens or houses, whereby the smaller animals may be trapped intheir pens.

More specifically it is our object to 'providesuch a gate, hinged at its upper edge in a gateway, and thereby adapted to swing to closed position by gravity, together with swinging stops pivoted to the gateway and adapted to be moved into the path oi swing oi' the gate on one side thereof to prevent vswinging oi' the gate beyond that side of the gateway.

A further object is to provide such stops for either side of the gateway, with which the swinging out the gate in either direction, or in both directions, may be limited. l

A urther object is to provide effective means or locking the stops in operative position'wliich can not be accidentally released bythe nosing oi' the hogs.

A still -liurther object is to provide such stops and locking means which are so arranged as to coact in their inoperative positions 'and lock the stops against accidental movement to operative positions by the nosing or the hogs.

A further object is to provide a gateway oli simple and durable construction comprising spaced upriglits connected by cross bars having extended portions adapted to be secured to the spaced posts outlining an open-- ing in a hog pen. p I

With4 these and other objects in view, our invention consists in the construction, ar-

rangement and combination of the various parts of my device, whereby the objects contemplated are attained, as hereinafter more fully set forth, pointed out in our claims and illustrated in the accompanying drawings, in which: l

Fig. 1 is an elevation of the device secured tothe postsin the opening of a hog pen.

Fig. 2 is a vertical sectional view-taken on the line 2-2 of Fig. 1. Fig. Sis a plan view of one side of the gate, and i' Fig. l is a sectional view taken on the line L1`4t of Fig. 1.

Farmershave been troubled somewhat .in raising hogs arrowed at dierent times by the injuring of the smaller hogs by those of fuller growth.l It has been found thatthe fall hogs,-kifor instance, do not dol as well Vwhen allowed to run constantly, and to sleep, with the spring pigs.

Anattempt has therefore, been made to segregate them in separate pens by themselves, especially during the night. In the daytime it is desirable to allowthe entire flock to'run free in the pastures provided for them. 'The driving of the hogs, however,-

into the individual pens, is a very arduous task, and it is practically impossible to .se-

lect all .of the -smallerhogs from the Hock and get them into their pens.

Our invention contemplates the-use of a gate adapted to selectively allow passage only of the smaller hogs, and prevent their returning. The smaller hogs may be lured into their pens by placing eed in the pens.

We have used the reference character 1()y to indicatethe posts detining the opening in such anr individual pen. Uur device comprises the gateway, A, and the swinging gate, B. rl`he gateway is formed of two uprights, 11, preerably ott wood, connected by the metallic bars, 12 and 13, which are extendedV beyond the uprights, 11, and provided at their ends withv openings, 14, through which the spikes, 15, may be inserted to connect the gateway to the posts, 10.

Embedded in the uprights, .11, is a hinge rod, 16, from which is swung the gate, 15. r1`he gate, B, comprises a sheet metal plate, 17, and the riveted hinge loops, 18, which receive the rod, 16. Sleeves, '19, space the gate froml the uprights, 11. A j

Fixed to the uprights, 11, and spaced away tlierefromby means of ,the bar, 18, and washers, 20, vare the keepers, 21. The keepers, 21, are secured by bolts, 22, passing, respectively, through the'fwashers', 20, andthe bai', 13. 'y

Pivoted to the uprights, 11, bymeans of f to' ahorizontal plane they are received by the keepers, 2l, and against the upper washers, 20, and project into the opening of the gateway so as to out the path of swing of the gate, B. The uprights, 1l, are of such width as to carry the bolts, 25, which serve to limit the movement of the stops, 2a,

in an upward direction to a position slightly beyond the vertical, as illustrated in dotted lines in Fig. i. Y

Pivoted to the uprights, l1, by means of bolts, 26, aligned with the keepers, 2l, and of suoli length thatV when depending-vertically, as illustrated, they snugly engage the upper edges of the stops, 2li, when in their operative position, as shown in Fig. 1, are the pawls, 27. rlfhe keepers, 21, are extended so as to receive the lower ends of the pawls, 27, when in depending position. The stops, 24, are of suliicient length and so situated relative to the pawls, 27, that the path of swing of their outer ends just clears the' circumference of the rounded end, 28, of the pawls, 27. f

vlt will now be seen that in moving the stops to inoperative position the paw127, may iirst be swung to the left, as indicated by the line, 30, until it no longer engages the stop, 24, when the stop, 24, may be swung upwardly, as indicatedby the line, 29. point will be reached when the stop, 24, will engage the pawl, 27, and push it on up beyond the dotted line position shown. The end of the pawl, 27 is notched, as at 81, to forin a shouider, 32, into which the end of the stop, 2li, is received when it has swung tothe dotted line position shown; After the stop, 24, is swung outwardly, it will Vpush the pawl, 27, upwardly until the notch, 3l, is reached, when the pawl, 27, will drop back to the position shown in dotted lines.

The bolts, 33, limit the upward movement of trie pawls, 27.

lt will now be seen 'that the stops, 24, on the side of the gate facing' within the pen may be raised to inoperative position, and the stops on the other side of the gate lowered to operative position when it is desired to trap the smaller hogs within their en'- closure.

By placing feed within the enclosure the farmer inayrleave the premises and theV smaller hogs will gradually be lured within the pen. rEhe stops kon the outside of the gate will prevent their returning and they will thereby be trapped within. the enclosure for the night so as to prevent their mingling with the larger hogs. The larger hogs will be excluded by the limited size of the opening in the gateway, A.

ln the morning when it is desired to allow .the smaller hogs to pasture, the stops on the outside may be raised.

If is desiredto use the pen for a farlrowing hog and to therefore Vexclude both the large and small animals, the stops on both sides of the gate may be lowered to operative position and the gate rthereby securely locked.

lt will be seen that the stops and pawls are peculiarly arranged to facilitate their manipulation. The operator may release one of the stops with the use of one hand by'placing the lingers under the' stop, and

swinging the pawl, 27, sideways with the` hind the keeper in order to prevent any possibility of the pawl, 27 being jarred laterally sui'ficient to allow the stop, 24;, to catch underneath the pawl.

The swinging pawl, depending by gravity into locking position is lalso advantageous in that though it may be nosed sideways by the hog, it will return to locking position when released. Were it possible for the pawl to be moved to inoperative position by the nosing of the hog, and to remain there, the latch might then also be moved to inoperative position. rlhe construction shown eliminates this possibility.

It will be seen also that the pawl and stop arrangement is such that when in inoperative position the saine condition exists, namely, that the .pawl would have to be moved against'its gravitational teiidency,.

and held there while the stop was'being moved in order to return the stop to operative position.

Sonie changes may be made in the construction and arrangement of the parts of our invention without departing from the real spirit and purpose of our invention, and it is our intention to cover by our claims any modified forms of structure or use of mechanical equivalents which may be reasonably included within their scope.
